    Abstract: In various embodiments of a method for filling root canal spaces, the root canal spaces are cleaned and irrigated, for example, by any suitable endodontic procedure, and the irrigating liquid is not removed from the canal spaces prior to filling. In some embodiments, a hydrophobic filler material is introduced into the root canal spaces while they are filled with liquid. As the canal spaces are filled, the hydrophobic filler material displaces the liquid and drives it out of the canal spaces, towards the crown of the tooth, where it can be removed. The hydrophobic filler material may comprise magnetically responsive particles having a hydrophobic surface coating that are compacted into the root canal spaces by application of a magnetic force field. In other embodiments, hydrophilic filler material in a flowable phase is introduced into the canal spaces where it partly displaces and partly absorbs the irrigating liquid before solidifying.

  • Publication number: 20130273495
    Abstract: A method and a device for effecting the cordless retraction of the gingival sulcus tissue that includes a cap or dam to be fitted onto a tooth. The well of the cap is pre-filled with a predetermined amount of a flowable non-setting kaolin based retraction material having a heavy viscosity or putty consistency. The preloaded cap is fitted to a prepared tooth so that when pressure is applied onto the cap, the retraction material is displaced under pressure and forced to flow into the sulcus, causing the gingival tissue to retract away from the tooth to enlarge the gingival sulcus. An internal ridge aids in retaining the retraction material within the cap.

  • Patent number: 8398397
    Abstract: Injection needle devices for administering a local anesthetic into tough, dense ligamentary tissue surrounding a tooth. The injection needle is a two-part needle that includes a proximal needle portion formed of metal, ceramic or rigid plastic and a distal needle portion formed of ceramic or hardened metal. The distal penetrating needle portion has an exposed length not more than about 8 mm, and an maximum outside diameter of about 25 gauge. At the transition between the proximal needle portion and the distal needle portion there can be an abrupt stop surface for limiting penetration through tissue. Alternatively, the proximal needle portion can have a tapered surface that permits penetration of the tapered surface into tissue. The injection needle device is designed to minimize pain and prevent buckling of the distal needle portion.

  • Patent number: 8388345
    Abstract: An endodontic activator is provided to facilitate the removal of pulp tissue, the smear layer, bacteria and related irritants from a root canal system. The activator is a sonically driven activator made from a strong, flexible, non-metallic, and non-cutting material. The activator can be smooth, flocked or brush-like. The activator comprises a snap-on coupler which is adapted to attach the tool to a driver without the use of tools. The activator can be provided with fluid passages which allow for irrigating reagents to be delivered into or vacuumed from the root canal space during endodontic procedures. By inducing sonic vibrations in the activator, hydrodynamic phenomena are induced in the solution in the root canal to enhance deep lateral cleaning of the root canal system of the tooth.

  • Publication number: 20120237893
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.
